What is the main focus and concern of demography?

What is the aim and purpose of demography?

Objectives of Demography: To achieve knowledge about the size, composition, organization and distribution of the population. To study the trend of population growth which describes the past evolution present distribution and future changes in the population of an area.

What is demography and its importance?

High fertility is connected to the child development. So, demography is concerned with the fertility and mortality and studies the birth and death rates. These health problems are solved by the demographer in the establishment of health planning of the country.

What are the four factors of demography?

Population growth is based on four fundamental factors: birth rate, death rate, immigration, and emigration.

What are the key concepts of demography?

The study of demography covers five basic topics: the size of the population; its distribution across geographic areas; its composition (e.g., age, sex, race, and other characteristics); changes in population size, distribution, and composition over time; and the determinants and consequences of population growth.

What are the five demographic processes?

Demography can be defined as the study of population, typically focused on five aspects: (1) size, (2) geographic distribution, (3) composition, (4) the components of change (births, deaths, migration), and (5) the determinants and consequences of population change (Swanson and Stephan, 2004, p.

What are the uses of demography?

Demography is widely used for various purposes and can encompass small, targeted populations or mass populations. Governments use demography for political observations, scientists use demography for research purposes, and businesses use demography for the purpose of advertising.

What is the importance of demography to public health?

Summary. Demography is the scientific study of human populations. It is important to understand the structure of a population in order to plan health and public health interventions; population structures can be represented as age pyramids. Population growth or decline depends upon fertility, mortality and migration.

What is the contribution of demography?

Around 50% of the demographic contribution is explained by the increase in the average productivity per worker (productivity component), which arises from the change in the population’s age structure and the rise in households’ saving rate.

Who is the father of demography?

A corner of history: John Graunt, 1620-1674, the father of demography.

Is demography a science?

Demography is the scientific study of human populations primarily with respect to their size, their structure and their development; it takes into account the quantitative aspects of their general characteristics.
